FortiClient DNS macOS Big Sur

Hello all, When the FortiClient connects, it retrieves the DNS that FortiGate gives it. I would then run my script that would allow me to update my resolv.conf to get my DNS first. It worked very well with FortiClient 5.6.6.755

sudo scutil <<EOF
d.init
d.add ServerAddresses 127.0.0.1 FORTIGATE_DNS
set State:/Network/Service/forticlientsslvpn/DNS
quit
EOF

Since the upgrade of FortiClient to version 6.4, the resolv.conf does not change anymore. even when manually testing the scutil command.

Could you please help me? Sincerely, vegasus

PS: I'm on macOS Big Sur 11.0.1
